摘要
以魏家地煤矿首采区(西一采区)为研究背景,根据矿井首采层瓦斯涌出规律,分析了瓦斯涌出量与煤层瓦斯含量、瓦斯涌出量与掘进长度的关系,从开采顺序、煤层厚度、区域构造、解放层开采四方面研究了开采条件对瓦斯涌出的影响,为矿井安全高效开采和煤层瓦斯的有效防控提供借鉴。
Based on the engineering background of first mining district（ West No. 1 district） of Weijiadi Coal Mine,according to gas emission law of the initial mining coal seam,the relationship between gas emission and coal seam gas content,as well as tunneling distance,was analyzed. The impact of mining conditions on gas emission was studied,from mining sequence,coal seam thickness,regional structure,and protective seam mining,to provide references for the efficient mining and effective coal seam gas control in coal mine.
